Overview
Brief Summary
The primary objective of this study is to evaluate the efficacy of Irinotecan Beads in combination with intravenous cetuximab versus intravenous irinotecan in combination with intravenous cetuximab in the treatment of patients with unresectable liver metastases from colorectal cancer.
Secondary objectives are safety and tolerability of hepatic chemoembolization and the question if the addition of aprepitant to standard antiemetic prophylaxis in patients treated by hepatic chemoembolization is safe and will reduce the rate of acute and delayed nausea and emesis.
Detailed Description
About half of patients with newly diagnosed colorectal cancer will develop metastatic disease and, however, in spite of the significant progress in the therapeutical strategies for metastatic disease, virtually all patients will eventually succumb to their illness. Based on prior clinical data there is a good rationale for the expectation that the combination of systemic chemotherapy and arterial chemoembolization with drug eluting beads may be effective in the setting of patients with unresectable or chemorefractory liver metastases. The aim of this study is therefore to assess whether the combination of Irinotecan eluting beads and intravenous cetuximab is safe and effective in the treatment of patients with unresectable liver metastases from refractory colorectal cancer and will result in a prolongation of disease control when compared to standard systemic treatment with intravenous irinotecan and intravenous cetuximab. In this patient group, intravenous irinotecan plus intravenous cetuximab may represent the "standard of care", with a previously described activity. The patient group is defined in terms of pretreatment, and the scientific question is whether the way of irinotecan administration by eluting beads in feasible and somehow beneficial.

Eligibility Criteria
Inclusion Criteria
- •Patients with confirmed diagnosis of stage IV (UICC) colorectal cancer with unresectable liver metastases (primary tumour may be present) and k-ras wild-type tumours

- •Patients with at least one measurable liver metastasis, with size \> 1cm (RECIST criteria)
- •Patients with liver only or liver dominant disease (defined as ≥ 50 % tumour burden confined to the liver)
- •Patients with a portal vein not interfering with transarterial chemoembolization (e.g. no thrombosis) as judged by the investigator
- •ECOG Performance status ≤ 2
- •Life expectancy \> 3 months
- •Age ≥ 18 years.
- •At least 4 weeks since last administration of last chemotherapy and/or radiotherapy (bone metastases may be allowed)
- •Patients who received VEGF-inhibition (e.g. with bevacizumab) in prior therapy are eligible if stopped since 4-6 weeks before randomization
Exclusion Criteria
- •Presence of CNS metastases
- •Contraindications to irinotecan therapy (Chronic inflammatory bowel disease and/or bowel obstruction, history of severe hypersensitivity reactions to irinotecan hydrochloride trihydrate)
- •Active bacterial, viral or fungal infection within 72 hours of study entry
- •Women who are pregnant or breast feeding
- •Allergy to contrast media
- •Presence of another concurrent malignancy. Prior malignancy in the last 5 years except adequately treated basal or squamous cell skin cancer or carcinoma in situ of the cervix
- •Any contraindication for hepatic embolisation procedures:
- •Large shunt as determined by the investigator (pretesting with lung perfusion scan not required)
- •Severe atheromatosis
